Willing to do anything to rope in Britney Spears as a judge in reality show The X factor, the bosses had conceded to her demands that she should be paid more than Jennifer Lopez was paid for adjudicating the first series of American Idol.
The Toxic singer eventually agreed to a $15 million payment for one season of the US version of the Simon Cowell-fronted talent show, $3 million more than the On The Floor hitmaker gained for her first season on the rival programme, reported TMZ.
"Britney's bottom line was no less than $13 million", a source said. However it is also believed she initially asked for as much as $20 million, before eventually settling on the final sum.
The deal is said to have made bosses on American Idol particularly nervous as they think Lopez now may up her demands for the show despite ratings falling in the last season.
It is believed X Factor bosses were so desperate to sign up Spears for the second season of the show they gave her permission to do whatever she wanted, which she did at her first taping of the show in Austin, Texas when she walked out during four auditions.
"Simon Cowell is a smart and shrewd businessman who knew Britney could make his show and he was willing to give her just about anything to come on board," a source said.
